This teeth whitening product is amazing!!!! I have had years of stains on my teeth despite regular cleanings and after a week I already saw amazing results. I made it apart of my night routine to avoid eating afterwards as you can't eat or drink for 20 mins after application. My co workers have all asked what I did as it's such a huge difference! It is totally worth every penny! Read more

I have crowns on my two front teeth, so while they stay pretty white, the ones around them start to yellow a bit after a while. This is the best way I’ve found to reverse that! I love that I can essentially “paint” just the teeth I want and that it’s not some super goopy gross mess (like the touch up tunes I get from my dentist). This has saved me a lot of money because I don’t have to buy from the dentist anymore and it gets my teeth back to where I want them :) Read more

The product definitely worked for me. The G-vial packaging is a manufacturer's trap to force you buy move gel. Squeeze the vial as hard as you can, and you still leave about 20-30% of the content inside the vial. I cut the vial open, inserted a Q-tip and pushed the gel out, enough for 2 more applications. I find it hard to believe this isn’t an intent from the manufacturer. Read more

I've used these before, and they seem to work as far as whitening goes, but the dispenser wastes a third of the gel. I end up cutting the tube with scissors to get all of it out. Read more

I'm so glad that the GLO Science teeth whitening device has refills so I can maintain my newly brightened smile! 5 treatments was enough to do the trick and get my teeth noticeably whiter, but I know that inevitably they'll lose their luster (probably due to my coffee habit). These refills are perfect for following up and maintaining the work I've already put it. They're convenient refills, shipping is quick, and I have them on hand for when I need them. I also want my husband to try the GLO device since his teeth tend to get stained easily, and of course GLO is washable and reusable. I bought this refill pack more for his benefit than mine, I just keep forgetting to remind him to use it (lol our memories make quite the pair). Looking forward to seeing his results now that I've seen how well it worked on my teeth. The teeth whitening gel doesn't taste as bad as a lot of the teeth strips I've tried, and it sticks to my teeth well. It really helps make the overall process as simple and user-friendly as possible. I'd highly recommend this, I just wish it had a subscribe and save option, because I will probably want to get a refill pack every 4-6 months for either myself or my husband. Read more

If you don't already have the GLO Teeth Whitening Kit then you HAVE TO HAVE IT! I ordered some refills as well because I am on Broadway and I use the teeth whitener every day. I feel like these will last me forever. Incredible product. I will never go back to any of the 15-20 products I tried before this. Read more

I have used the Glo System for 5+ years. Itsworks very well. But lately, I have been very disappointed with the vials. The older style I ordered in 2015 which included 10 original vials (Great To Get 10), but the whitening gel was very runny and did not smell nor taste like the ones I had been getting for years. This time I ordered the G-vial shown here which only has 7 in the package and is much more expensive!. My disappointment is that it is so hard to squeeze the gel out of the vial, (very hard to do this), and there is always gel left in the vial and this is a huge waste and really causes the product to cost more than the $53+. Does anyone have a solution as to how to get the full benefit of each vial. I am very disappointed with this. Thanks for any feedback. Can Amazon let the vendor know? Thanks, DebS Read more

It took a couple uses to be able to keep it "in place". Since they're not strips you have to play a game to keep your saliva from washing it away or just swallowing it. In a day I noticed it greatly diminished stains that a leadimg brand strip did not even phase. Stains were completely gone end of day two, using 3x a day. Read more

I have the mouthpiece that lights up from this brand so I love these for when I need refills. Amazing price. They are cheaper here than in “beauty” stores. One thing though, make sure you take the tube apart when you think it’s empty. There is a lot more product you can get out. I have very VERY sensitive teeth and all other whitening products cause pain and sensitivity to even air, but I’ve never felt any pain or sensitivity with these. As long as they make these, I will buy them. 10 vials will last you a long time. When I use these I can usually get several shades whiter after about 5-6 days. Read more

Had to discontinue use after 2 days. WRECKED my gums all the way around. Very easy application and I try to keep my mouth open for 10 minutes to let it activate before closing my mouth and letting the saliva dilute it. However, after closing my miuth the gel comes in contact with your gums all around. It damages the gums so badly that it feels like the gel chemically peeled off a few layers - leaving it very sore and tender. Also, it claims to show results after every use. 2 days and 8 applications later I saw no difference. Read more

Glo works very well.I believe the new gel kits are a big improvement over the original kits - amount of gel, taste, better applicator. My teeth are much whiter. The price is not cheap, but the effect is worth it. Read more

Good product. Easy to use. Works pretty well. Noticeably whiter after 10 consecutive uses Read more
